The effective connection of the arrival flight and the departure flight of the airport is beneficial to the formation of flight waves, and the flight waves are the objective reflection of the compact transit connection of the airline company in the airport.
The study of the flight wave changes the connectivity of the air transport network from a single spatial dimension to a dual spatial and temporal dimension.

Specifically, a flight schedule of an airport to be identified, which is prepared to establish a flight wave system, is obtained, the arrival time of each arrival flight of the airport and the departure time of each departure flight from the airport are obtained from the flight schedule, the arrival time information and the departure time information are screened, once the arrival time information and the departure time information fall into any time window range, the corresponding arrival flights and departure flights are respectively placed into an arrival flight data set and a departure flight data set, the transit connectivity detection is carried out on the two sets according to the transit flight type and the preset transit interval under a specific scene, the number of transit arrival flights and the number of transit departure flights in any time window range are further obtained, and finally, based on the obtained number of transit arrival flights and the number of transit departure flights, as the time windows are multiple, therefore, the corresponding relation between the number of the transferable arriving flights and the number of the transferable departing flights and the time can be established, namely, a time curve graph of the distribution of the number of the transferable arriving flights and the number of the transferable departing flights in a longer time period is drawn, whether the arriving wave and the departing wave are synchronous or not is judged according to the time curve graph, and the wave crests and the wave troughs are regularly distributed in the time periods. And acquiring the recognition result of the airport flight wave system according to the corresponding relation, and judging whether the airline company forms the flight wave system at a certain airport.
According to the embodiment of the invention, the arriving flight and the departing flight meeting the corresponding conditions are screened in the time window range, the effective transfer connection flight data set is established, the change characteristics of the arriving wave and the departing wave are analyzed and mined, the flight wave system is further identified, and the accuracy of flight wave identification is greatly improved.
On the basis of the above embodiment, the obtaining a flight schedule of the airport to be identified further includes:
screening national airports based on the passenger throughput, and acquiring a plurality of airports to be identified with the top passenger throughput rank;
and screening the airline company to be identified with the largest number of the departure and landing flights at the airport to be identified based on the number of the departure and landing flights of the airline company at the airport to be identified, and acquiring a flight schedule of the airline company to be identified.
The flight schedule specifically includes a flight number, a departure airport, an arrival airport, a departure time, an arrival time, and the like.
Specifically, prior to establishing the flight wave system, the relevant information and data are initially screened. The first is the hub airport to be identified, i.e. the airport to be identified. Because the airport has larger passenger throughput which is an important basis for constructing flight waves, the national airport passenger throughput is obtained according to data such as statistical civil aviation, traffic statistics bulletin of various regions, Chinese city statistics yearbook and the like, and the hub airport to be identified is screened according to the passenger throughput. According to the embodiment of the invention, the airport with the top 10 ranking in China is screened as the hub airport to be identified according to the throughput of the airport passengers.
And further screening the comprehensive transport capacity of each airline company within the range of the selected hub airport to be identified. Research shows that only large airlines have the capacity of constructing a flight wave system at a hub airport, so that the embodiment of the invention acquires the number of flights executed by each airline company of the hub airport according to a national flight schedule, determines several large airlines ranked at the top according to the number of the flights, and screens flight schedule data of the large airlines, including information such as a flight number, a departure airport, an arrival airport, departure time, arrival time and the like.
On the basis of the foregoing embodiment, the method further includes, before step S2:

wherein the time center point of the kth time window isThe kth time window isIminMinimum turnaround time interval for international flight, ImaxFor the maximum flight transfer interval of an international flight, DminMinimum turnaround time interval for domestic flights, DmaxThe maximum transfer time interval for domestic flights.
Specifically, the time window is defined by a time center and a time interval between the time center and the time of the engine, and the time included in the time window is set to be the time center tcIs distributed in an axisymmetric way. Firstly, considering the time required by passenger to transfer to the airplane, respectively setting a minimum transfer time and a maximum transfer time, wherein the minimum transfer timeThe flight time is to ensure that the passenger has enough time to transfer, and the maximum flight time is to reduce the uncertainty of waiting for the passenger. Then classifying the flights into international flights and domestic flights, and setting the maximum transfer time of the international flights as ImaxMinimum turnaround time is Imin(ii) a The maximum transfer time of domestic flights is DmaxMinimum turnaround time is Dmin. Fig. 2 is a schematic diagram of a time window according to an embodiment of the present invention, and as shown in fig. 2, the time points in the time window are defined according to the following:
(1) the earliest international arrival flight at t1At the moment, the transfer flight can be at the earliest time t6From which it may be at the latest at time t7Starting with tcIs a center of and t1The symmetrical time points are set as t8；
(2) With tcAs a center, the earliest domestic arrival flight at t3At time, the transit flight may be at time t at the latest5Starting;
(3) with tcAs a center, the latest domestic arriving flight is at t4At the moment, the transfer flight can be at the earliest time t5And (5) starting.
After the setting of each time point is completed, a calculation formula of each time in the time window can be obtained as follows:
t1＝tc+0.5Imin-Imax，
t2＝tc-0.5Imin，
t3＝tc+0.5Dmin-Dmax，
t4＝tc-0.5Dmin，
t5＝tc+0.5Dmin，
t6＝tc-0.5Dmin+Dmax，
t7＝tc+0.5Imin，
t8＝tc-0.5Imin+Imax。
based on the concept of a flight wave, a flight wave system refers to a plurality of continuous flight waves formed by all flights of an airline at an airport for a long period of time, for example, one day. Setting two adjacent time centersAndis T minutes, the number of time centers in a day N is 1440/T, for the time centerCorresponding time window interval isI.e., [ t ]1,t8]. Generally, the transit time of international flights is longer than that of domestic flights, so the embodiment of the invention adopts the following data for calculation: t is 5min, Imin＝90min，Imax＝210min；Dmin＝60min， Dmax＝150min。
On the basis of the foregoing embodiment, in the method, step S3 specifically includes:

Specifically, after setting a time window and each time point in the time window, the number of flights that can be transferred to and arrive in the k-th time window is recorded as AkAnd the number of departure flights in the kth time window is recorded as DkWhere k is 1,2, …, N.
